}

Input for creating a child session.

Fields

parent_session: Session

child_id: String

title: String

responsibility: String

assignment_prompt: String

subagent_type: String

model_override: Option<String>

Optional model override resolved from subagent_type routing. When None, the child inherits the parent session’s model.

model_ref_override: Option<ProviderModelRef>

Optional provider+model override resolved from subagent routing. When present, this preserves cross-provider routing for child execution.

runtime_metadata: HashMap<String, String>

Runtime metadata resolved from subagent routing (e.g. external agent config).

system_prompt_override: Option<String>

Optional system prompt override resolved from the SubagentProfileRegistry. When None, the child falls back to the legacy hard-coded prompts (PLAN_AGENT_SYSTEM_PROMPT for subagent_type == "plan", CHILD_SYSTEM_PROMPT otherwise) so that callers that have not yet been wired up keep their pre-PR-3 behaviour byte-for-byte.

auto_run: bool

Whether to immediately enqueue the child for execution. Defaults to true.

reasoning_effort: Option<ReasoningEffort>

Optional reasoning effort to apply to the child’s own LLM calls. None (the default) leaves Session::reasoning_effort at None, so the provider falls back to its default. The child does NOT inherit the parent’s reasoning_effort — fan-out children that only need a quick lookup should not pay for xhigh reasoning just because the orchestrator is running at xhigh.
